Carpet cleaning machine

Abstract

A muffler for a steam cleaning apparatus comprising a housing having a first and a second inlet, and an outlet, a plurality of baffles disposed within, and coupled to the housing, wherein the plurality of baffles are covered with a foam; wherein the first inlet is pneumatically coupled to an air pump of the steam cleaning apparatus, and wherein the first inlet provides to the housing a stream of humid air from an application subsystem of the steam cleaning apparatus; and wherein the second inlet receives combustion exhaust from a combustion motor that drives an air pump that is operationally coupled to the application subsystem, and wherein the outlet releases air comprising combustion exhaust of the motor.

Description

I. FIELD OF THE INVENTIONThe inventive subject matter herein relates generally to machine cleaning which can be adapted to carpets, drapery, blinds, upholstery and the like.II. BACKGROUND OF THE INVENTIONCarpets, draperies, blinds, upholstery and the like are often cleaned using steam / hot water systems. Since these units usually operate on similar principles, but at different pressures and with different solvents, they are all generically and interchangeably referred to herein as carpet cleaners, carpet cleaning machines, systems, equipment, units and so on. In general, steam / hot water systems include the same basic components, namely a wand for dispensing and recovering a cleaning fluid, an optional reservoir for holding reserve fluid, a fluid pump for providing pressurized cleaning fluid at the wand, an air pump (sometimes referred to as a vacuum pump) for sucking up spent fluid, and a spent fluid holding tank. Carpet cleaning equipment contemplated herein ranges from relatively s...

Problems solved by technology

First, an operator may keep his equipment in a poor state of maintenance.

For example, the holding tanks may not be emptied regularly, or the equipment may not be serviced regularly.

Second, operators tend to push their equipment to the limit, for example by setting the thermostat on the heater at an unsafe level.

Third, operators do not necessarily know how to operate the equipment properly.

This problem can be addressed to some extent with operator manuals, but such manuals are of little use where the manuals are not available at an operating site, or an operator is unwilling to wade through a manual to find the relevant section.

Fourth, operators do not necessarily keep accurate records of operating conditions, so that when an equipment failure occurs it is often almost impossible to pinpoint the cause as being something which is or is not covered by warranty.

Fifth, when equipment failures do occur, the equipment may be at a great distance from a suitable repair facility, and individual operators may not have the skills to effectiv
